Learning is optimized when we fail 15% of the time -- ScienceDaily

As a junior varsity high school tennis coach I tell the players that they should look at losing matches as an opportunity to learn what they can do to improve their game. (I tell myself that too when I play tennis matches.) If the players can learn from losses they still win in the long run even though they lost the latest match. (I’d also say they can also learn from wins by looking at what they can improve. I do this by keeping a journal in which I rate whether I improved in technique, tactics and mental parts of my game and rate what needs to be improved.)

The Science Daily article links to a paper titled The Eight Five Percent Rule for optimal learning that is fairly technical. The Science Daily article summarizes:

Educators and educational scholars have long recognized that there is something of a "sweet spot" when it comes to learning. That is, we learn best when we are challenged to grasp something just outside the bounds of our existing knowledge. When a challenge is too simple, we don't learn anything new; likewise, we don't enhance our knowledge when a challenge is so difficult that we fail entirely or give up.

So where does the sweet spot lie? According to the new study, to be published in the journal Nature Communications, it's when failure occurs 15% of the time. Put another way, it's when the right answer is given 85% of the time.

So we optimize our learning if we fail about one out of six times. Good to know!

I believe these results parallel what it takes to achieve a state of mind that is called Flow, a concept identified by Mihaly Csikszentmihalyi, a Hungarian-American psychologist. The Wikipedia entry describes flow as “the mental state of operation in which a person performing an activity is fully immersed in a feeling of energized focus, full involvement, and enjoyment in the process of the activity. In essence, flow is characterized by the complete absorption in what one does, and a resulting loss in one's sense of space and time.”

I say that there is a connection between optimal learning and flow because achieving a flow state requires facing a task that challenges you without being daunting. The Positive Psychology website explains: “an optimal Flow state was created when people tackled challenges that they perceived to be at just the right level of ‘stretch’ for their skill sets. In other words, neither too tough nor too easy as to be boring.”

Putting together the findings on optimal learning and flow it appears that both need a “Goldilocks” challenge: one that stretches you to achieve flow and reveals what you need to improve for the next time.

Lessons from the NFL AFC Championship

-->

I know many people outside of New England are tired of seeing the New England Patriots playing in the Super Bowl. There are a lot of reasons why the Pats dominate so much but I believe we can apply a couple things Tom Brady said in the post-game interview of the 2019 NFL’s AFC Championship (in which the New England Patriots beat the Kansas City Chiefs 37-31). We can apply these ideas not just to sports but how we live. I’ve provided his response to a reporter’s question with key words in bold.

Q: How do you stay so calm in the biggest moments, especially when your team is down and you have to drive the team right back?

BRADY: “Part of playing sports is just staying in the moment. We always say one play at a time and you can’t make up for things that happen in the past. You just have to think about what you are going to do moving forward. Start of the fourth quarter, they scored. We are up three to start the fourth quarter. What a great opportunity to be against this team and to be ahead three in the fourth quarter with a chance to win is pretty sweet. They blew so many teams out this year. It is just a great opportunity for us, and we took advantage of it.”

His first point, staying in the moment, is key. I’ve seen players and teams get desperate or angry when losing or when calls go against them then try for plays or shots that aren’t part of their normal repertoire. They’re upset about what just happened then try to make up for it by hitting the ball harder or going for shots they don’t “own.” For instance, in tennis (the sport with which I’m most familiar because I play it almost daily) I’ve seen players go for a shot or an angle that they normally wouldn’t try if they were ahead. Instead, they often end up making an unforced error, which only makes things worse. (I know because I’ve done it!) 

As Brady says it’s better to forget about past mistakes or calls that go against you and focus on two things: stay in the moment while thinking of what you’re going to do next. One tip I use in tennis after making a mistake is to tell myself, “Next time” while making a couple shadow swings on how I wanted to hit the shot that I just missed. “Next time” means I’m telling myself I’ll do it better the next time I have the chance. This attitude implicitly represents a focus on the process rather than the results. It also reflects their confidence in themselves. And, it also means that their self-esteem isn’t tied to the outcome. Sure, it doesn’t feel good to lose but someone like Brady or Federer just use the loss as motivation to learn from what happened and try to improve. (This also reflects something I’ve written about in a previous post: the difference between having a growth mindset rather than a fixed mindset.)

Later Brady said that the Pats had a “great opportunity” when starting the fourth quarter with a three point lead over a team that was seeded #1 and had beaten other teams by large margins. I find it interesting that he didn’t say it was a challenge or that they were nervous. This is one of the qualities I’ve noticed with champions like the Brady, the Patriots or, switching to tennis again, Roger Federer. They are unflappable.  They see facing a tough opponent as an opportunity to excel rather than a challenge for which they might not be good enough.

So what accounts for this calmness? I’d say these factors: focus on the present, confidence in yourself without tying the outcome to your self-esteem and a process-oriented mentality. 

Tennis Reminders (Updated)

In an earlier post, Can I? versus I Can!, I shared results of research on how people performed when they asked themselves the question “Can I do this?” versus coaxing themselves with “I can do this!” I mentioned that I apply this by asking myself “Can I play well today?” then answering “Yes!”

At the end of that post I also mentioned that I also use the acronym LIFE³ as part of my pre-match routine to remind why I’m playing: to Learn, Improve, have Fun and to Express myself, to Explore my capabilities and to Exercise.

The final pre-match self-talk covers key reminders on the techniques I want to use. I use two phrases, one for groundstrokes and one for serving. For groundstrokes I say, “Watch me Catch Butt.” This actually contains three reminders in one. Watch: reminds me to watch the shadow of the ball. Why the shadow? To narrow my focus to something specific on the ball, not the ball itself. (I actually don’t watch the ball over its entire flight. More on that in a later post. Hint: has to do with something called saccadic eye movements.) Catch: reminds me that on my forehand I’m holding my left arm across my body and basically parallel to the baseline as if I’m going to catch the ball. This forces me to turn my upper body, which sets up the coil needed to generate power. On the backhand I pretend I’m going to catch the ball with the butt of my racket. On volleys Catch reminds me to set up my racket as if I’m catching the ball with it. Butt: reminds me to pull the racket through contact to help generate racket speed.

Finally, when serving, I use the word UP to remind myself that I’m hitting Up on the ball and to Pronate.

By the way, in case you were wondering, here is a little background on my tennis playing ability and experience. When I’ve taken tennis lessons in the past couple years I’ve asked the four different instructors how they’d rate me on the NTRP (National Tennis Rating Program) scale. All of them say I’m at least a 4.0, maybe a little higher. Of course, all of them say this is based on what they see during lessons and that the rating could change depending on how I play in actual matches.

I constantly study the game by watching YouTube videos, reading many books and subscribing to a bunch of email newsletters of pros and instructors such as Wil Hamilton, Clay Ballard, Brent Abel, Peter Freeman, Ramon Osa, Jorge Capestany, and Ian Westermann. For the last three years I also have kept a tennis journal in which I rate myself whether I made incremental improvement in technique, tactics and my mental/emotional state. The journal also records observations on areas that need to be worked on for the next match.

I also use the Babolat POP wrist sensor to track my strokes. The POP collects average and maximum speeds of groundstrokes and serves, the kinds of groundstrokes (top spin, slice or flat) and gives an overall rating based on spin, speed and style. (I record this information in a spreadsheet to look for trends.)

All of this information aims to show that even though I might not be a 4.5 or higher rated player my constant study has resulted in my game continuing to advance. I believe I’m playing better now at the age of 67 than I have ever played before in the 50+ years that I’ve played this sport. And I’m not done!

UPDATED 1/2/2019

Since writing this a year ago I've tweaked and added to my pre-match routine. The UP reminder for serving now is PUPSS which stands for Point at the toss, hit Up, Pronate, start the serve take back Slowly and try to keep my body Sideways longer. I added these to my pre-serve reminder because I was finding myself starting the take back too fast then stopping or slowing down and my body was opening to the court too early which I think caused my first serve to go into the net too often.

The following might sound hokey but I also ask why am I playing. The answer is LIFES. This stands for to Learn more about the game and myself, to Improve, to have Fun, to Explore, get Exercise, have Excitement and Express myself with Style. The Style reminder is to get me to focus on playing smoothly and on the process of hitting the ball rather than the results. I got this idea after reading Gabriele Wulf’s Attention and Motor Skill Learning in which she describes the results of her research on the difference between having an external focus rather than an internal focus in performing athletic skills.

Here is how Amazon summarizes her book. “Attention and Motor Skill Learning challenges traditional views that the method of learning a motor skill involves focusing attention on each part of the skill and internalizing proper execution. Instead, author Gabriele Wulf argues that the learning of new motor skills suffers when attentional focus is on the coordination of movements. When attention is directed to the desired movement effect, however, performance levels rise. Not only is a higher level of performance often achieved faster with an external rather than an internal attention focus, but the skill is retained better.”

Her book discusses experiments she conducted with people doing a variety of skills such as standing on a balance bar and trying to keep it steady. The internal group was told to try to keep their feet as steady as possible while the external group was told to try to keep two lights that were on the balance beam as steady as possible. The external group consistently did better than the internal group and maintained this advantage when tested days or weeks later.

You could argue that my emphasis on making my shots with style actually is an internal focus but I would say it’s more of an external focus. By thinking about making my strokes with smooth style I’m thinking about the result, not on the mechanics of how to play with style. And I’m thinking mostly about how the forehand, backhand or serve look when they’re completed rather than the whole stroke. Bottom line: I think it works, at least for me!

What Separates Champions From ‘Almost Champions’? -- Science of Us

What Separates Champions From ‘Almost Champions’? -- Science of Us

I’m going to start of with a long series of quotes from an article in The Cut titled “What Separates Champions From ‘Almost Champions’?

It’s the perennial million-dollar question of nature versus nurture, sure. But the difference between the greats and the almost-greats (which, by the way, applies well beyond sports) also appears to be at least partially driven by one specific thing — how each group responds to adversity. The greats rise to the challenge and put in persistent effort; the almost-greats lose steam and regress.  

For a recent study published in the journal Frontiers in Psychology, talent development researchers Dave Collins, Aine MacNamara, and Neil McCarthy examined the differences between athletes who overcame adversity and went on to become world-class (what they call super champions) and those who struggled in the face of hardship (the hearthbreakingly named “almost champions”) . Whereas super champions were playing in premier leagues and/or competing on national teams (think: Olympics), almost champions had achieved well at the youth level but were playing in the less prestigious leagues as adults. 

The researchers found that super champions were characterized “by an almost fanatical reaction to challenge.” They viewed challenges in a positive light — as opportunities to grow — and overcame them thanks to a “never satisfied” attitude. This runs in contrast to almost champions, who blamed setbacks on external causes, became negative, and lost motivation.
.... 

Super champions were driven from within. Their primary concern was self-improvement. They held themselves to high standards, but judged themselves against prior versions of themselves, not against others.
Almost champions, however, were focused on external benchmarks, like national rankings or how they compared to rivals, a mind-set the researchers speculate why almost champions got discouraged during rough patches.  

....... 

World-class performers, then, don’t rely on either nature or nurture, but on a combination of the two — and they are really good at nurturing their nature. All of which suggests the recipe that gives rise to super champions is worth emulating: Individuals who demonstrate persistent effort follow their interests; practice foremost to get better, not to outdo others; derive satisfaction from within; and feel constantly supported, but not pressured, in their journey toward achievement. If these criteria are in place, experiencing failure doesn’t weaken motivation — it bolsters it. In the words of Michael Joyner, an expert on human performance at Mayo Clinic, “With enough persistent effort, most people can get pretty good at anything.”

These results touch on a number of topics I’ve covered in previous posts: having a growth mindset versus a fixed mindset, focusing on the process rather than results, focusing inwardly on how you’re performing per your own standards instead of worrying about how you’re being perceived externally by your opponent or your friends, engaging in deliberate practice to improve, not just repeating what you already do well and not pushing yourself in practice and having grit as a personal quality. The Cut article doesn’t specifically touch on all of these points while I think they’re all implicitly involved.

I figure someone reading all of this might ask how studying world-class performers applies to us. How many of us really fall into that category? I know it will sound arrogant or obnoxious but I like to think I applied these ideas when designing and delivering presentations when I was working, in my tennis game and in other areas of my life such as relationships, etc. While I’ll probably never climb to the A level of players at the clubs where I play I do know my game has continually improved thanks to my constant investment into getting better. I like to think I’m now a B+ player! ;-) That’s why I believe the quote at the end of the article is key, which is why I’m repeating it below.

In the words of Michael Joyner, an expert on human performance at Mayo Clinic, “With enough persistent effort, most people can get pretty good at anything.”

Amen!

Coaching Junior Varsity High School Tennis: 2nd Year Observations

This spring I completed the second season of coaching a boy’s junior varsity team for a local Catholic high school. Although I haven’t coached a high school sport before I have coached town and club soccer teams from Under 12 up to U18 teams. However, as you can imagine none of the drills and exercises I used for coaching soccer helped with coaching tennis. The only commonalities shared by both centers on my general preference for coaching. This includes finding ways to set up practices so that the players aren’t standing around in lines waiting for their turn, keeping instructions short and to the point rather than long lectures, and not having the players run laps. (No lines, lectures or laps.) Fortunately for me, the varsity coach (who started at the same time as me) has coached high school tennis for 15 years and designed most practices for both varsity and JV.

In any case, I’m glad to say that the JV record for the two seasons I’ve coached was 6 wins and 6 losses in 2017 and 7 wins and 4 losses in 2018. For what it’s worth here are some conclusions and lessons I learned from these two seasons.

1.        Relative coaching pressures between varsity and JV. While varsity plays to have a good enough record to qualify for the end of season state tournament, JV doesn’t have the same tournament. (At least that’s true here in Massachusetts. I don’t know if this is true in other states.) That doesn’t mean I don’t care about the win-loss record. I know the boys (and their parents) do keep track of how they’re doing. This gave me the freedom to experiment with different lineups without being unduly concerned about the results.

2.        Statistics. I use a spreadsheet to track the win-loss match record of each player as well as the number of sets won or lost and total number of games won or lost. I also tracked how many times each boy played an exhibition match. (Exhibition matches are those that we play after the initial three singles and two doubles matches that determine which school won that day. With 11 players on my roster and 7 playing official matches I had 4 extra players who would play exhibition matches with the extra players of the other team.) I also tracked the win-loss record of the different doubles teams so that I knew which teams were stronger.

3.        Coaching technique. You’d think the fact that we worked with the boys five days a week for ten weeks that the varsity coach and I could work on their technique. However, we usually had 2 or 3 matches a week, leaving only 2 or 3 days a week for practices. Plus it was difficult spending too much time with any one player when you have 11 or 12 at the practice. So the best we could do is make some suggestions. (I liken it to the difference in what you can learn in taking a tennis clinic versus a private lesson.) We had a couple players who asked for specific help on a specific stroke like their backhand or serve. For them we’d have the player stay after practice so we could work with them. The bottom line: we spent more time working on singles and doubles tactics.

4.        Chalk talk sessions. We started try-outs and practices in the third week of March. However, New England weather often forced us to cancel practice or run them in a basketball gym, which limits the amount of tennis-like activities you can run. When forced indoors the varsity coach and I would use foam balls or low-pressure balls to work on technique. Sometimes I would have JV meet in a conference room where I could go over some of the info I shared with them in emails and to explain handouts showing positioning in singles and doubles.

5.        Designing practices. I mentioned above that I was lucky to have an experienced varsity coach (who also instructs at a local tennis club) who designed the practices. Still, there were times when I was on my own because varsity had a match while JV didn’t. I was frustrated when looking for ideas on designing practices in the various books I have as well as coaching web sites. Most of the drills and games offered in these sources involve only 1 to 4 players. I wanted to create practices that involved everyone, if possible. One of my solutions was to use a game-based approach in which the boys played singles or doubles games but with conditions I imposed to get the boys to play in a certain way. For example, I set a condition where all of the players had to be inside the lines of the court after the serve. This encouraged them to play a bit more aggressively instead of retreating behind the baseline and playing defensively all of the time.

6.        Pre-match talks. While I tracked individual win-loss record in addition to the team’s win-loss record I never talked about winning or losing during the pre-match team talk. Why? Because I know that the players can’t control whether they win or lose. They can only control how the thought and effort they put into their play. I came up with a mantra that I repeated before each match: Give 100% effort (or take no points off), act strong and poised regardless of the score, enjoy the competition (because it shows where you can improve and what you do well), and learn from every mistake and every match.

7.        Between the points ritual. I told the boys that they spend more time getting ready to play the next point than they do actually playing the point. To help the boys focus between points I recommended a three-step process: Review, Rehearse, Relax. When the point ended I recommend that the player review what happened, especially if it was an error. Then rehearse what you wanted to happen by taking a couple shadow swings while visualizing the shot they wanted to make. Relax by taking a couple deep breaths while looking at their string dampener.

8.        Importance of team captain. The team elected the same team captain in both seasons. He turned out to be a great asset. I had him introduce the players to the opposing teams but also had him organize getting parents to volunteer providing drinks and snacks for our home matches. He also ran the warm ups before practices and matches. He also told me if he knew certain guys would not be able to attend a practice or match due to illness, school commitments, etc.

9.        Team emails. In addition to using the school email system to inform the boys of the upcoming practice and match schedule I’d also use the email to share important information on technique and tactics from a variety of sources such as web sites or email newsletters from a variety of online coaches. I’d also print out key diagrams as handouts.

10.    Parent emails. From talking with the parents who would come to watch their son play at home matches I learned that the amount of information the boys shared with their parents varied wildly. Some parents had no idea how the team was doing or what we worked on during practices. While I know I don’t need to cater to the parents I also know they’re more likely to complain to the Athletic Director if they don’t know what is going on with the team (in general terms). I’m not talking about giving parents a blow-by-blow accounting of everything we do. But I figure it helps to explain my coaching philosophy and provide some key information on tactics and techniques to make them feel a bit more comfortable. It appears I struck the right balance because all of the input received from the parents has been positive.

11.    Cheat sheet. I’m not sure why I saved this for the final point but I distilled key points for singles, doubles and general tips into one double-sided sheet. We covered this sheet during our chalk talk sessions and referred to it sometimes during the pre-match talks. It was an interesting process whittling the tons of info I have into what I think are the most important.

That’s it!

Can I? versus I Can!

Having read many self-help books over the years I’ve constantly encountered the idea of using positive self-talk and affirmation statements to help improve your chances of achieving your goals. Many of these books tell you to write positive “affirmation” statements. Examples would be:

• I have plenty of creativity for this project.
• I am successful.
• I complete tasks and projects on time.
• I expect to be successful in all of my endeavors. Success is my natural state.

A tennis example could be, "I always play my best" or "I love competition and do well."

When I read these books years ago and tried affirmations I believe they helped put me in a more positive frame of mind. However, as I wrote in my April 23, 2017 post “Moving Beyond Positive Thinking”, research has shown that if we vividly visualize our goals our mind doesn’t know the difference between the imagined outcome and the actual results! We can end up having less motivation not more. In this post I referred to work done by Gabriele Oettingen, professor of psychology at New York University and the University of Hamburg and covered in her book Rethinking Positive Thinking: Inside the New Science of Motivation.

Daniel Pink, author of books such as Drive: The Surprising Truth About What Motivates Us and To Sell Is Human: The Surprising Truth About Moving Others, reports on research that says we can be more productive by asking if we can do something then answering with a “yes” rather than declaring “I can do it.” Pink describes research done on a method used by Bob the Builder, an “overall-clad, stop-motion animated construction executive – who debuted on CBBC in 1999 and whose television programme now reaches children in 240 territories and 45 languages – is a management radical. His approach to directing projects, people and himself runs counter to the prevailing wisdom about business performance.”

Most of us believe in positive self-talk. "I can achieve anything," we mouth to the mirror in the morning. "Nobody can stop me," we tell ourselves before walking into a big meeting. We believe we'll do better if we banish doubts about our ability or our strategy and instead muster an inner voice that affirms our awesomeness.

But not Bob. Instead of puffing up himself and his team, he first wonders whether they can actually achieve their goal. In asking his signature question – Can we fix it? – he introduces some doubt.

…

In a nifty set of experiments, three social scientists explored the differences between what they call "declarative" self-talk (I will fix it!) and "interrogative" self-talk (Can I fix it?). They began by presenting a group of participants with some anagrams to solve (for example, rearranging the letters in "sauce" to spell "cause".) But before the participants tackled the problem, the researchers asked one half of them to take a minute to ask themselves whether they would complete the task – and the other half to tell themselves that they would complete the task.

The results?

The self-questioning group solved significantly more anagrams than the self-affirming group.

…

By asking "Can we fix it?", Bob widens the possibilities. Only then – once he's explored the options and examined his assumptions – does he elicit a rousing "Yes, we can" from his team and everyone gets to work.

So the next time you're feeding your inner self a heady brew of confident declarations and bold affirmations, toss in a handful of interrogatives with a few sprinkles of humility and doubt.

The research that Pink reports relates somewhat to Oettingen’s WOOP process. WOOP stands for Wish, Outcome, Obstacle, and Plan. You define what you wish [W] to accomplish, determine the outcome [O], identify the likely obstacles [O] then design a plan [P] to overcome those obstacles.

Am I saying not to use positive affirmations? No! I think they have a place. For an interesting perspective see Scott Adams’ How to Fail at Almost Everything and Still Win Big: Kind of the Story of My Life. Adams in hardly a raving advocate of positive mental attitude but he admits to have tried positive affirmations. I think the key take away is not to expect affirmations to have magical powers that will make things happen without work or without accounting for obstacles that could derail your efforts. We need to have a positive idea where we want to go while also asking ourselves what could go wrong and what can we do to deal with it.

By now you’re probably wondering, “How does this apply to tennis or other sports?” Here’s how it applies for me. When I step onto the court I ask myself a version of Bob the Builder’s question: “Can I play well today? … Yes!” (I also use the acronym LIFE³ to remind why I’m playing: to Learn, Improve, have Fun and to Express myself, to Explore my capabilities and to Exercise.)
